Abstract: The application concerns a computer-implemented image manipulation apparatus and method 200 configured to receive an input image 202 and a desired style to be transferred to the input image. The method can obtain a representation 204 of the input image selected from a plurality of stored representations of a plurality of images, wherein each said representation comprises data describing a set of image features. The method can modify at least one of the set of image features in the obtained representation to correspond to the input image and/or the desired style to produce a modified representation 207, and render a reference image 209 based on the modified representation. A manipulated image is generated by performing a style transfer operation 210 on the input image using the rendered reference image.

Abstract: Provided is a method of processing a 360-degree image that includes: obtaining a plurality of motion vectors for a 360-degree image, determining at least one motion vector, which indicates global rotation of the 360-degree image, among the plurality of motion vectors through filtering; performing three-dimensional-transformation on the determined at least one motion vector so as to acquire three-dimensional rotation information of the 360-degree image, and correcting distortion, of the 360-degree image, caused by shaking, based on the acquired three-dimensional rotation information.

Abstract: Provided is an electronic device for stabilizing a 360-degree video, the electronic device including a memory storing one or more instructions, and a processor for executing the one or more instructions stored in the memory, wherein the processor is configured to execute the one or more instructions to: when a 360-degree video is reproduced, allocate probability values to a plurality of pixels included in a frame of the 360-degree video, based on a possibility that each of the plurality of pixels is included in a user's field of view (FOV), determine a three-dimensional (3D) rotation for the 360-degree video, based on the allocated probability values, and generate a stabilized 360-degree video by applying the 3D rotation to the 360-degree video.

Abstract: An image manipulation method comprises receiving an input image 202 and obtaining a set of image content descriptors for the input image 204. A data store of related images is then accessed and a group of stored images 208,210 based on similarity between the set of image content descriptors of the groups of stored images and the set of image content descriptors of the input image to retrieve a stored image 216 that is used as a reference image when generating a manipulated image by performing a style transfer 218 operation on the input image. The data store is created based on analysis of activities of at least one user in relation to images. An additional invention of creation at least one data store adapted for image manipulation is also claimed.

Abstract: An apparatus for determining configuration settings for a display apparatus comprises: a unit to determine configuration settings (e.g. using a machine learning algorithm) for a display apparatus in dependence on one or more first input parameters (e.g. content descriptors or environmental parameters such as background noise, acoustic property or ambient lighting parameters) indicative of one or more conditions that affect a user experience when viewing content reproduced on the display apparatus; means to predict an expected user response (e.g. predict if the user’s attention is captured or predicting an emotional response) as a result of operating the display apparatus according to the determined configuration settings; an updating unit configured to search for an updated set of configuration settings that are expected to produce a user response that is closer to an intended result than the predicted user response; and a display apparatus controller configured to cause the display apparatus to operate according to the updated configuration settings.

Abstract: Stabilising 360 degree video by assigning probability values S202 to each pixel of one or more frames of a 360 degree video. The probability is based on the likelihood that the pixel will be included in a field of view when the video is reproduced. This is followed by determining a three-dimensional rotation for stabilising the 360 degree video based on the assigned probability values S203 and outputting the video S204. Preferably the probability values are based on historical viewing data S201. Preferably the probability values are based on: the type of object in which the pixel is included; a depth property; the visual importance of a region; a motion vector associated with the pixel a contour in a saliency map of the frame; or a location of the pixel in relation to one or more sound sources. In another embodiment the probability value of the pixels is determined using a machine learning algorithm. Preferably the machine learning algorithm is trained using historical viewing data.

Abstract: Apparatus and methods are provided. The method includes receiving content that comprises at least one 360 degree image. The method also includes applying a rotation to the at least one 360 degree image to increase a compression ratio, when a compression algorithm compresses the at least one 360 degree image that is rotated, relative to another compression ratio achieved when the compression algorithm compresses the content without the applied rotation to the at least one 360 degree image. The method also includes compressing the content including the at least one 360 degree image that is rotated based on the compression algorithm. The method further includes outputting the compressed content and a rotation parameter that defines the applied rotation.
